hi all, I got java.lang.NullPointerException when I was calling a simple ejb3 staless session been (deployed to jboss4.04GA) from my servlet, my web application and the ejb were packeged in the same ear. during the deployment I can't see a local jndi binding for this bean as well. just wodering, do I need to configure something for this bean in ejb-jar.xml or jndi.properties as I think by default session beans will bind to JNDI in the form ejbName/remote for remote interfaces and ejbName/local in the case of local interfaces here is the ejb interface: package src.reg.server; | import javax.ejb.Local; | | @Local() | public interface token { | | public String issue(String uid, String PIN); | } here is the implementation: package src.reg.server; | | import javax.ejb.Stateless; | import javax.persistence.EntityManager; | import javax.persistence.PersistenceContext; | | @Stateless() | public class tokenAction implements token { | public String issueKey(String username,String pin) | { | String temp = username +pin; | return temp; | } | } this is the servlet where I invoke the EJB bean; | package src.reg.server; | | import java.text.*; | import javax.servlet.*; | import javax.servlet.http.*; | import java.io.*; | import javax.ejb.EJB; | | public class myservlet extends HttpServlet { | | @EJB | private static token t; | private String key = null ; | | protected void doPost(HttpServletRequest req, HttpServletResponse resp) | throws ServletException, | IOException { | resp.setContentType("text/plain"); | PrintWriter out = resp.getWriter(); | String uid = req.getParameter("uid"); | String Pin = req.getParameter("passwd"); | key = t.issueKey(uid, Pin);//(here is the exception was thrown) out.println(key); | } | | } thanks a lot...
